Versuchsvorschrift

2-Chloro-5-nitropyridine (5 g, 31.5 mmol) and hydrazine (1.74 g, 34.7 mmol) were dissolved in 60 ml of dioxane, and the solution was stirred at room temperature for 16 hours. The precipitated yellow powder (m.p.: 198°-208°0 C.) was collected by filtration to obtain 502 mg of the intended product as a hydrochloride salt.
